mfd: mc13xxx: Add missing spi_setup()
The probe routine should call spi_setup() to configure the SPI bus
so it can properly communicate with the device.

This patch simplifies probe() and remove() functions by moving

mfd: mc13xxx: Remove unnecessary spi_set_drvdata()
The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the

mfd: Drop modifying mc13xxx driver's id_table in probe
This was introduced in commit
876989d (mfd: Add device tree probe support for mc13xxx)
for spi and later while introducing support for i2c copied to the i2c
driver.
Modifying driver details is very strange, for example probing an
mc13892 device (instantiated via dt) removes the driver's ability to
handle (traditionally probed) mc13783 devices in this case.
I'm not aware of any problems that make this hack necessary and if
there were some, they'd have to be fixed in the spi/i2c core, not in
a driver.

mfd: mc13xxx workaround SPI hardware bug on i.Mx
The MC13xxx PMIC is mainly used on i.Mx SoC. On those SoC the SPI
hardware will deassert CS line as soon as the SPI FIFO is empty.
The MC13xxx hardware is very sensitive to CS line change as it
corrupts the transfer if CS is deasserted in the middle of a register
read or write.
It is not possible to use the CS line as a GPIO on some SoC, so we
need to workaround this by implementing a single SPI transfer to
access the PMIC.
